The 1920-S Mercury Dime is worth anywhere from $4 in heavily worn condition to over $1,500 or more in high mint state grades. If you found one of these coins in an old jar or inherited collection, you’re holding a piece of early 20th-century American history — and it might be worth more than you think.
What Is the 1920-S Mercury Dime?
The 1920-S Mercury Dime was struck at the San Francisco Mint and carries the iconic “S” mintmark on the reverse side, just to the left of the “ONE DIME” inscription. Designed by Adolph Weinman, this dime features Lady Liberty wearing a winged cap — often mistaken for the Roman god Mercury, which gave the coin its popular nickname.
The Mercury Dime series ran from 1916 to 1945, and the 1920-S is considered a mid-series date with a moderate mintage of around 19.17 million coins. While not a rare key date like the 1916-D, the 1920-S still commands respectable prices in better grades. It’s made of 90% silver, which gives even worn examples some intrinsic metal value beyond their collector appeal.

How Much Is a 1920-S Mercury Dime Worth?
The value of a 1920-S Mercury Dime depends heavily on its condition, also called “grade” in collector terms. A coin that’s been in circulation for decades will look very different from one that was saved right away — and that difference can mean hundreds of dollars.

What Makes Some 1920-S Dimes More Valuable?
Beyond basic grade, there’s one feature collectors specifically look for on Mercury Dimes: the Full Bands (FB) designation. On the reverse, the fasces design features a bundle of rods wrapped with two horizontal bands. When those bands are fully and clearly separated — not flattened by wear or a weak strike — the coin qualifies for the Full Bands designation.
A 1920-S Mercury Dime with Full Bands can be worth significantly more than a non-FB example in the same grade. For instance, an MS-65 without FB might bring $400, while an MS-65 FB could fetch $800 to $1,200 or more.
This is a detail that’s easy to miss with the naked eye. CoinKnow is a great tool here — it helps everyday collectors identify grade-affecting details like band separation, making it easier to understand whether your coin has premium value.

How to Grade Your 1920-S Mercury Dime at Home
Grading coins at home isn’t an exact science, but you can get a solid general sense of your coin’s condition with a few basic steps. Start by examining the coin under good lighting — a small magnifying glass or jeweler’s loupe helps a lot.
Look at the high points of the design first: Liberty’s cheek, the hair above the ear, and the diagonal bands on the reverse fasces. These areas show wear first. If they’re smooth and flat, the coin is likely in the Good to Fine range. If you can still see fine hair strands and the bands have some definition, you’re probably looking at an Extremely Fine coin.
For a more precise estimate, you can explore detailed 1920 Mercury Dime value information by grade and mintmark to compare your coin with known examples. Professional grading services like PCGS or NGC provide the most accurate and trustworthy assessments if you think your coin is worth $100 or more.

CoinKnow also offers a handy grading reference feature that lets you compare your coin’s images against graded examples, which is especially useful when you’re just starting out.
Silver Melt Value and Why It Matters
Even if your 1920-S Mercury Dime is too worn for collector appeal, it still has real value as silver. Each Mercury Dime contains approximately 0.0723 troy ounces of pure silver. When silver prices are around $30 per ounce, that gives every Mercury Dime a melt value of roughly $2.15 to $2.50.
So even a heavily worn coin isn’t worthless. The collector premium on top of the silver melt value is what can push a nice example into the hundreds or thousands of dollars. It’s one of the reasons Mercury Dimes remain popular with both collectors and silver stackers alike.

Frequently Asked Questions
Q: Where is the mintmark on a 1920-S Mercury Dime?
A: The mintmark is located on the reverse of the coin, to the left of the “ONE DIME” inscription, near the bottom of the fasces bundle. An “S” indicates the coin was made at the San Francisco Mint.
Q: Is the 1920-S Mercury Dime rare?
A: It’s not considered a rare coin — nearly 19.17 million were minted. However, finding one in high uncirculated grades, especially with Full Bands, is genuinely difficult and adds significant value.
Q: Should I clean my 1920-S Mercury Dime before selling it?
A: No — please don’t clean it. Cleaning a coin removes its natural surface patina and can reduce its value dramatically. Even light polishing can drop a coin’s grade and cost you money. Leave it as-is and let a professional assess it.
